That font-size style setting is also affecting the toolbar, making it too tall on tundra. Claro added a {{{font:medium}}} rule to fix the toolbar height problem but makes the toolbar label font too big.
I'm guessing the style=""..."" setting was only supposed to affect the editor contents? If that's changed to not affect the toolbar then the tundra height problem will be fixed and the claro font-size: medium clause can be removed, fixing the font problem too.
Arguably setting a font-size shouldn't affect the Toolbar height when it's not displaying labels, but the main issue seems to be where that style=""..."" tag is applied.
